Description

Technical Field

[0001] The present invention relates to the technical field of tobacco leaf scanning, and in particular to a tobacco leaf scanning device with controllable temperature and humidity. Background Art

[0002] Tobacco leaf grading is a highly hands-on task, and flue-cured tobacco samples vary across tobacco regions across the country. However, local tobacco leaf grading training sessions can conflict with each other, making it impossible for graders to attend every session. Because traditional tobacco leaf samples undergo changes in color and luster over time, missing a training session wastes valuable training opportunities and samples.

[0003] Traditional tobacco leaf grading training typically creates the necessary environmental conditions by controlling the temperature, humidity, and light source throughout the training room. However, due to the large size of the training room, while tobacco leaf samples occupy only a small area within the room, the accuracy of the environmental conditions for the tobacco leaf samples cannot be guaranteed. Furthermore, it takes a long time for the training room's environmental conditions to stabilize, resulting in low accuracy and efficiency in setting environmental conditions.

[0004] Furthermore, to record tobacco leaf sample information, the traditional method is to take photos of the samples with a mobile phone. However, due to the beautification and distortion of mobile phone photos, and the differences in photo quality between different mobile phones, the accuracy of the captured images cannot be guaranteed.

[0032] Example 1

[0033] Figure 1 This is a structural schematic diagram of a temperature and humidity controllable tobacco leaf scanning device provided in the first embodiment of the present invention. This embodiment is applicable to situations where the environmental conditions required for tobacco leaf sample grading are efficiently and accurately set.

[0034] like Figure 1As shown, the device includes: a box 1, a frame 2, a temperature and humidity regulator 3, an imaging device 4, a lamp 5, a transparent partition 6, a temperature and humidity control panel 7, an imaging control panel 8 and a microprocessor 9; wherein: the interior of the box 1 is a cavity, and the box 1 includes at least one movable box surface; the frame 2 is connected to the box 1 for supporting the box 1; the box 1 is provided with a temperature and humidity regulator 3, a transparent partition 6, a microprocessor 9, at least two imaging devices 4 and at least one lamp 5; the microprocessor is connected to the imaging device for processing the image taken by the imaging device; the microprocessor is connected to the target database via a network for The image processing results are uploaded to the target database for storage; a temperature and humidity control panel 7 and an imaging control panel 8 are provided on the outside of the box 1; the temperature and humidity regulator 3 is used to adjust the temperature and humidity inside the box 1, the transparent partition 6 is used to support the target tobacco leaf sample, the imaging device 4 is used to shoot the target tobacco leaf sample from multiple angles, and the lamp 5 is used to provide a target light source for the inside of the box 1; the temperature and humidity control panel 7 is connected to the temperature and humidity regulator 3, and is used to receive the target temperature and humidity information and control the temperature and humidity regulator 3 to be turned on or off; the imaging control panel 8 is connected to the imaging device 4, and is used to control the imaging device 4 to be turned on or off.

[0035] The microprocessor disposed within the housing is electrically connected to the imaging device and can be used to receive multi-view images captured by the imaging device and generate corresponding three-dimensional images based on the multi-view images as image processing results. For example, the three-dimensional images corresponding to the multi-view images can be generated based on computer vision and three-dimensional reconstruction technology, or based on deep learning technology. For example, the three-dimensional reconstruction technology can be multi-view stereo (MVS) technology or three-dimensional reconstruction software (such as Reality Capture, Photoscan, etc.).

[0036] The microprocessor is connected to a target database via a network and is configured to upload image processing results to the target database for storage. The target database can be used to store the image processing results transmitted by the microprocessor. Exemplarily, the target database can be a relational database (such as MySQL, PostgreSQL, etc.), a NoSQL database (such as MongoDB, Couchbase, etc.), an object storage service (such as AWS S3, Google Cloud Storage, Azure Blob Storage, etc.), or an image database.

[0037] The frame and the box body are mechanically connected, for example, they can be fixedly connected or non-fixedly connected, and can play a supporting role for the box body. The box body includes a total of six box surfaces, at least one of which is a movable box surface, and the rest are fixed box surfaces. The movable box surface can be opened, and the fixed box surface cannot be opened. For example, the number of movable box surfaces can be one or two, and the two movable box surfaces can be opposite side box surfaces of the box body. Exemplarily, the shape of the box body can be a cuboid or a cube. Specifically, the interior of the box body is a cavity, and a temperature and humidity regulator, a transparent partition, at least two imaging devices and at least one lamp are provided inside the box body, and a temperature and humidity control panel and an imaging control panel are provided outside the box body.

[0038] Among them, the temperature and humidity regulator can be used to adjust the temperature and humidity inside the box to reach the set temperature and humidity. The transparent partition can be used to support the target tobacco leaf sample, and the target tobacco leaf sample can refer to the tobacco leaf object that needs to be graded. For example, the target tobacco leaf sample can be a sheet tobacco or a bunch of freshly flue-cured tobacco. It should be noted that in this embodiment, there is no specific limitation on the material, composition form and placement of the transparent partition, and it can be flexibly set according to actual needs. For example, the transparent partition can be a glass plate, an acrylic plate, a PC (polycarbonate) plate or a PVC (polyvinyl chloride) plate, etc. Exemplarily, the transparent partition can be composed of a partition, which is placed in the central position inside the box parallel to the top surface (or bottom surface) of the box; it can also be composed of multiple (such as 3) partitions connected to each other at a certain angle and connected to any box surface of the box.

[0039] Among them, multiple imaging devices can be set on different box surfaces inside the box, or on the same box surface inside the box, and face the target tobacco leaf sample placed on the transparent partition with different shooting angles, so as to shoot the target tobacco leaf sample from multiple angles. For example, the imaging device can be a camera or a camera. For example, a camera can be set on the top surface, bottom surface, left surface and right surface of the box to shoot the target tobacco leaf sample from four different angles. Lamps can be used to provide a target light source for the inside of the box, for example, the lamps can be lamp tubes or light bulbs. Optionally, the color temperature setting range of the target light source is 5300-5800K, and the illumination setting range of the target light source is 1800-2200Lx. It should be noted that this embodiment does not specifically limit the number and placement of the lamps, and can be flexibly set according to actual needs. For example, one or more lamp tubes can be set on the top surface and bottom surface of the box.

[0040] Among them, the temperature and humidity control panel supports touch screen control and key control. It is electrically connected to the temperature and humidity regulator and can be used to receive target temperature and humidity information input via touch screen or keystrokes, and transmit the target temperature and humidity information to the temperature and humidity regulator to control the temperature and humidity regulator to open and adjust the temperature and humidity inside the box according to the target temperature and humidity information. Among them, the target temperature and humidity can refer to the temperature and humidity inside the box that need to be set. Optionally, the target temperature and humidity information include target temperature and target humidity. The setting range of the target temperature is 20-24°C, and the setting range of the target humidity is 65%-75%. Among them, the imaging control panel can also support touch screen control and keystroke control. It is connected to the imaging device and can be used to receive the imaging device start signal input via touch screen or keystrokes to control the imaging device to open. It should be noted that when the temperature and humidity control panel does not receive the target temperature and humidity information, the temperature and humidity regulator is controlled to be in the off state by default; when the imaging control panel does not receive the imaging device start signal, the imaging device is controlled to be in the off state by default.

[0041] See also Figure 1 The tobacco leaf scanning device shown includes a box and a frame for supporting the box. Among them, the six box surfaces include a movable box surface that can be opened. The box is equipped with four cameras, four light tubes, a microprocessor, a temperature and humidity regulator, and a transparent partition composed of three partitions. The outside of the box (specifically, the outer side of the box) is equipped with a temperature and humidity control panel and an imaging control panel. Among them, one camera is respectively set on the top, bottom, left and right sides of the box (distributed symmetrically), and two light tubes are respectively set on the top and bottom sides of the box (distributed symmetrically).

[0042] In this embodiment, optionally, Figure 2 As shown, a lamp control panel 10 is further provided on the outside of the box 1 , and the lamp control panel 10 is connected to the lamp 5 , and is used to receive target light source information and control the lamp 5 to turn on or off.

[0043] Specifically, the lamp control panel also supports touchscreen control and keypad control. It is electrically connected to the lamp and can be used to receive target light source information input via the touchscreen or keypad. It can then control the lamp to generate the target light source based on the target light source information, thereby providing the target light source inside the cabinet. Similarly, if the lamp control panel does not receive the target light source information, the lamp is controlled to be off by default.

[0044] In this embodiment, optionally, Figure 2 As shown, a power supply device 11 is further provided inside the housing 1, and the power supply device 11 is connected to the imaging device 4 and the lamp 5 to provide power to the imaging device 4 and the lamp 5. For example, the power supply device can be a battery, a USB power supply, or the like.

[0045] In this embodiment, optionally, Figure 3 As shown, an image display 12 is also provided on the outside of the housing 1. The image display 12 is connected to the microprocessor 11 and is used to display the image processing results of the microprocessor 11. Specifically, the microprocessor provided inside the housing processes the multi-view images captured by the imaging device to generate corresponding three-dimensional images, and the image display provided outside the housing can display the three-dimensional images in real time.

[0046] The technical solution of an embodiment of the present invention provides a tobacco leaf scanning device with controllable temperature and humidity, including a box body, a frame body, a temperature and humidity regulator, an imaging device, a lamp, a transparent partition, a temperature and humidity control panel, an imaging control panel and a microprocessor; wherein: the interior of the box body is a cavity, and the box body includes at least one movable box surface; the frame body is connected to the box body for supporting the box body; the interior of the box body is provided with a temperature and humidity regulator, a transparent partition, a microprocessor, at least two imaging devices and at least one lamp, and the microprocessor is connected to the imaging device for processing images taken by the imaging device; the microprocessor is connected to the target database via a network for uploading the image processing results to the target database for storage; the outside of the box body is provided with a temperature and humidity control panel and an imaging control panel; the temperature and humidity regulator is used to adjust the temperature and humidity inside the box body, the transparent partition is used to support the target tobacco leaf sample, the imaging device is used to shoot the target tobacco leaf sample from multiple angles, and the lamp is used to provide a target light source for the interior of the box body; the temperature and humidity control panel is connected to the temperature and humidity regulator for receiving target temperature and humidity information and controlling the temperature and humidity regulator to be turned on or off; the imaging control panel is connected to the imaging device for controlling the imaging device to be turned on or off. The present technical solution may include the following beneficial effects: providing a smaller placement space for tobacco leaf samples, and setting the required environmental conditions for tobacco leaf sample grading through the temperature and humidity regulators and lamps inside the box, which can improve the accuracy and efficiency of the environmental condition setting; at the same time, multiple imaging devices inside the box are used to shoot tobacco leaf samples from multiple perspectives, making imaging more accurate and efficient, so that the status of tobacco leaf samples can be observed in all directions, and the multi-perspective images shot by the imaging device are processed by the microprocessor set inside the box to generate corresponding three-dimensional images, and the three-dimensional images are stored in the target database, which can effectively preserve the relevant information of tobacco leaf samples in the form of images for a long time, so that quality inspectors can review and compare them at any time.

[0047] Example 2

[0048] Figure 4 This is a structural diagram of another temperature and humidity controllable tobacco leaf scanning device provided in the second embodiment of the present invention. This embodiment is optimized based on the above embodiment.

[0049] like Figure 4As shown, a temperature and humidity sensor 13 is also provided inside the box 1 for detecting the temperature and humidity inside the box 1; a temperature and humidity display 14 is also provided outside the box 1, and the temperature and humidity display 14 is connected to the temperature and humidity sensor 13 for displaying the temperature and humidity inside the box 1.

[0050] Specifically, in this embodiment, the temperature and humidity inside the box can be detected in real time by a temperature and humidity sensor, and the detected temperature and humidity inside the box can be displayed in real time by a temperature and humidity display, so that the staff can understand the temperature and humidity conditions inside the box in real time. The staff can input the target temperature and humidity information through the temperature and humidity control panel, which then transmits the target temperature and humidity information to the temperature and humidity regulator. The temperature and humidity regulator adjusts the temperature and humidity inside the box according to the target temperature and humidity information, so that the actual temperature inside the box reaches the target temperature and the actual humidity reaches the target humidity. The staff can also input the target light source information through the lamp control panel, which then transmits the target light source information to the lamp and controls the lamp to emit the target light source, so as to provide the target light source inside the box.

[0051] After setting the temperature, humidity, and light source environment inside the box, the staff can place the target tobacco leaf sample on the transparent partition inside the box and then input the imaging device start signal through the imaging control panel to control the imaging device to start. The target tobacco leaf sample is photographed from different perspectives by multiple imaging devices to obtain multi-perspective images, and the captured multi-perspective images are transmitted to the microprocessor. After receiving the multi-perspective images transmitted by the imaging device, the microprocessor can automatically generate a corresponding three-dimensional image based on the multi-perspective image and transmit the three-dimensional image to the image display so that the generated three-dimensional image can be displayed in real time on the image display. At the same time, the three-dimensional image can be transmitted to the target database via the network for data storage, so that the relevant information of the target tobacco leaf sample can be effectively preserved in the form of images for a long time, which not only ensures the representativeness of the tobacco leaf sample, but also ensures that each quality inspector can review and compare it at any time.

[0052] The technical solution of the embodiment of the present invention can detect the temperature and humidity inside the box in real time through the temperature and humidity sensor arranged inside the box, and can intuitively display the temperature and humidity inside the box detected by the temperature and humidity sensor in real time through the temperature and humidity display arranged outside the box.
